Abstract
The yield of crude hemicelluloses extracted from oil palm frond OPF Elaeis guineensis was 33.04 of the total of OPF dry weight. Hemicellulose was fractionated into hemicellulose A HA 62.17 and hemicellulose B HB 37.83. Composition analysis revealed that xylose was the major monosaccharide present in hemicelluloses followed by arabinose and glucose. Hemicelluloses were further studied by solubility rheological and thermal fiS analysis in three types of pH condition 3 7 and 10 and the results are reported. It was found that hemicelluloses presented the highest solubility in alkaline condition compared to acidic. Both hemicelluloses exhibited more pronounced shear thinning behavior and showed higher viscosity in acidic pH solution. Besides that HB fraction was less affected by pH compared to HA. Thermal analysis showed that the variety of pH was also affected the thermal properties of hemicelluloses.
